ULTRA LOW DISTORTION
Distortion so low that it defies measurement,
even with the finest distortion analyzers At mid-
frequencies, 8 ohm load, the distortion meter reads
the residual distortion of the oscillator ( 0002%) with
or without the MC7300 in the circuit. This means
the amplifier distortion is lower than the analyzer is
capable of measuring
BALANCED INPUTS
Modern technology has made it possible to build
preamps and amplifiers with the high signal to noise
ratio necessary to reproduce the sound quality
present on compact discs However, the
interconnecting cables can pick-up electrical
interference from other equipment or appliances The
balanced inputs on the MC7300 provide a minimum
of 40dB more protection against such noise pick-up
WIDE POWER BANDWIDTH
Full power output capability well above and
below the frequencies that can be heard by humans
POWER GUARD
The exclusive Mclntosh circuit that prevents
harsh sounding clipping and protects your speakers
from damage
THERMAL PROTECTION
Thermal sensors that turn off the AC power if
improper loading or ventilation causes the amplifier to
over heat
REGULATED ILLUMINATION
The tremendous peak output power capability of
the MC7300 has made the addition of a circuit that
regulates the brilliance of the illumination necessary
When there are high power output demands, the line
voltage may sag, however this new circuit prevents
the panel lights from dimming
TURN ON DELAY
The MC7300 has a circuit that delays amplifier
operation for about two seconds after turn on This
prevents pops or thumps generated in other
equipment from causing annoying noises or damaging
your speakers
OUTPUT AUTOFORMERS
The unequaled expertise of Mclntosh in the
design and manufacture of output transformers is
legendary in the Hi Fi industry In the MC7300 they
provide proper matching for 2, 4 and 8 ohms loads in
stereo and 1,2,4,8 and 16 ohms in mono They
protect your speakers from damage in the event of an
output transistor failure, provide low distortion power
transfer at frequencies well beyond human hearing
and deliver peak output currents in excess of 85
amperes
MODULAR CONSTRUCTION
If service should be required,
construction makes repairs easier
modular
